7 Application mea Augus'w, 18s?. serial No. 246,146. (No model.)

` l.To all whom, it maynconcern.- Y Be it known that I, IsAAo N.HOADLEY, a citizen of the United States, residing at Brad-v ford, in thecounty ofyMcKean and 'State of 5 Pennsylvania, have invented certainnewand useful Improvements in Packersv for Oil and Gas Wells, of whichthe following is a specication. In small wells where the oil-supply isonly a few barrels a'day and the casing has become worn and rusted, orin wells where it is necessary to shut ofi salt or freshwater from anysource, it is important while shutting oft' the water from the welltoyet allow the gas to -es- 'A 15 cape, this beingessential to theproper work-v ing of the pump.

- My improvement 'therefore relates to that form of packer whichisintended rfor use in f, connection with two pipes in an oil-welkome 2ointended to carry oft' thc'oil and the other the gas, and the packer isof such construction as to becapableof location at any desired heightinthewell. l v ,y l

In the accompanying drawings, Figure I is a vertical section of aportion of oil'and gas pipes bearing my improved packer. Fig; II is asectional perspective view of the yguide for the gas-pipe, the lowerend-of the gas-pipe being shown about to enter its seat. Fig. III 3o isa vertical sectional View of a modified form of theinvention, intendedfor use where the weight of the small pipe is not sufficient to'set outthe packing.

l'may represent a portion of one section of i the oil-pipe, and 2 acoupling-thimble on the llower end of such section. This couplingthimblemay be lat the base ofthe oil pipe if thel section 1 be the lowermostsection of the pipe,

or it may serve for the attachment of additional sections'of pipe if thepacking is to be located at any desired distance abovethe bottom of thewell. Y A

The packing is shown' at 3, being made 'of rubber, in customarycylindrical form, and

rests by a metal flange, 4, on the thimble 2.

The upper flange, 5, serves as a followerjncompressing the said packing.The flanges 4 5 and the packing surround loosely the pipey 1, so as tobe out of frictional contact there- 5o with. l

' 6 is the gas-pipe havingprolongations 7 vand embracing such sectionofAthe oil-pipe,

'packing has reached the desired position, either The section 8' isrigidly screwed into the up- 'per ange, 5, above the packing 3, 4but atits s lower end passes loosely through the iiange 4, [Y below thepacking. A couplingfthimble, 9,

on the lower'end of section 8 serves for the 'attachment'ot' additionallengths of gas-pipe, if desired. Into the flange 5 above the secytion 8the section 7 of the gas-pipe is screwed, I Vand upon its upperl endthis section supports 6c a metallic guide, 10, which has an arm, 11, ofelliptical or oval form, arranged in inclinedA position, as shown, so asto practically till the ,oil-well transversely, and having a passage,12, and seat 13, with rubber Agasket 14 for the gas-y 65 pipe 6. Theupper surfaceof the arm 11 is hollowed out slightly, as shown, so as toguide the lower end of the gas-'pipe to its seat. l The following is themethod of operation:

They packer consists of the packing 3, and 7oy flanges4 5 having beenplaced upon the proper section of the oil-pipe, with the guide. 10 11,supported by the section 7, on the flange 5,

the latter is lowered into the welly until theV at the bottom or at anyheight above the -bottom which maybe desired. The-gas-pipe 6, havingv atits lower end a thimble, 15, is then lowered into the well. On coming incontact with the guide 11 said gaspipeis directed-toward the seat 13 insaid guide, and rests upon the rubber gasket 14 inthe bottom thereof. A-practically-continuous gas-pipeis thus provided from beneath thelower4fiauge, 4, of the packing to the top of the well. The weight of thegas-pipe,resting upon the gasket 14 and therefrom'upon the flange5,'-compresses the Packing 3 between the flanges 5 and 4, thus exv9o lpanding it against the'sides'of thewelland preventing water inktheuppervportion of thev well from access to the oil below. Y. There is no Ytrouble in removing this packer, as by lifting the small pipe from itsseat the duid abovethe seat 13 in the guide 10 falls through the lowersections of the pipe, thus taking all pressure ott of the packing. Asthe uid runs in, ita, Y can be pumped out before thetubing ris re-lmoved'. J y j d It will be 4seen that with this packer in use thetubingcan be hung from the casing-head.

In the form shown in Fig, III,.I have illus-v trated a method in whichthe expanding mechanism shown in my pending application, No.226,267,1iled February 2, 1887, may be applied to this invention. Heretherotation of the oil-pipe is intended to effect the setting out of thepacking in cases Where the Weight of the small pipe is insufficient forthis purpose.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

1. The combination, with the oil-pipe and a gas-pipe, one of which beingin two or more sections, of a packing surrounding said pipes, a flangeabove and below said packing and supported by one of said pipes andadapted to compress said packing, the guides 10 and 11, supported by theupper ange and having a seat adapted to receive the upper section of thesectional pipe, substantially as set forth.

2. The combination, with the packing, the

` oil-pipe, and a iiange surrounding said pipe and adapted to compresssaid packing, of the gas-pipe made in sections, a guide having aperforated arm surrounding the oilpipe,land a seat, one section of thegas-pipe carrying said guide and supported upon said flange, and agasket in said seat adapted to support the upper sections of the pipe,as set forth.

3. The combination, with an oil-pipe and a gaspipe, one of which beingin two or more sections, of a packing surrounding said pipes, flangesabove and below said packing supported by one of said pipes and adaptedto compress said packing, one section o f the sectional pipe beingscrewed into the upper flange, the guide 10 l1, supported by saidsection, a gasket, and a seat in said guide, in which said gasket rests,adapted to receive the upper section of the said pipe, substantially asset forth. 4o
